Abstract

The initial design of a wideband non-dispersive wire bow-tie antenna using GA is presented here, primarily for microwave imaging application. The wire bow-tie antenna is designed to operate from 4 GHz to 8 GHz which is essential for microwave penetration into biological tissue. Backscattered signal is then received and analyzed to detect any possible object within the medium. Resistively loading method is implemented to reduce late-time ringing cause by the antenna internal reflections. Results with optimised antenna geometry and different number of resistive loads are presented and compared with and without existence of scatterers. Prototype of the design has also been developed and the experimental results are presented alongside with the simulations outcome.
